String#scan with a block may do what you want:

>> "_foo_ _bar_".scan(/_(\w+)_/) { |x| puts "Offset #{$`.size}, captures 
#{x.inspect}" }
Offset 0, captures ["foo"]
Offset 6, captures ["bar"]
=> "_foo_ _bar_"

But it doesn't give you offsets to the individual captures, just to the 
start of the whole match. (You also get the full match in $& and the 
rest of the string after the match in $')
